This is false.
9/12 in it's lowest terms is 3/7.
1/sin^2x-1/tan^2x=
1/sin^2x-1/ (sin^2x/cos^2x)<<sin tan= sin/cos>>
= 1/sin^2x- cos^2x / sin^2x
= (1- cos^2x) / sin^2x <<combining into a single fraction>>
sin^2 x / sin^2x <<since 1- cos^2 x sin^2 x
=1
this simplifies to 1.
The result will be 34.561
Let me = the minutes we are searching for.
(-2.5)/11_1/4 = 1/m
Rewrite 11_1/4 as 45/4.
(-2 5)/(45/4) = 1/m
Cross-multiply to find m.
45/4 = -2.5m
Divide both sides by -2.5.
45/4 ÷ -2.5 = m
Use your calculator and good luck.
There are 0-14 numbers inclusive, so that means there are 15 scraps of paper.
Probability of getting greater than or equal to six (6, 7, 8, 9, 10, 11, 12, 13, 14) is
(as there are 15 scraps)
so the answer is C.
